UNITE@ will Application filed lleptefa in connection with the windows ot automobiles.

The object of the invention is the provision of a novel mechanism oit the class described which is simple and inexpensive in its construction, composed oi iew parts and capable of being easily attached as a unit to a window trame.

The invention is fully described in th following speciiication, and while in it broader aspect it is capable ot embodimcn in numerous Ytoi-ms, two embodiments only thereof are illustrated in the accompanying drawings, in which,

Fig. 1 is a l'ragmentaiy onterside ele vation of a window trame and associated window, with the latter in partly lowered position, and with a mechanism embodying the invention associated therewith, parts ot the frame and control mechanism being in section. Fig. 2 isa similar view otn a slightly modiiied form oil the invention, and Figs. 3 and i are enlarged sections on the lines 3-3 and d i, respectively, in Figs. 1 and 2.

Referring to the drawings, 1 designates a window Aframe forming the window opening 2 in its upper portion and a chamber 3 in its lower portion into which latter the glass or other window member d may be lowered from Vclosing' relation to the opening, as is customary in the windows of automobiles and the like.

At the upper inner side ot the chamber 3 is located the customary loclnboard 5, which extends crosswise of the inner trame from side to side thereof. A bracket plate 6 is screwed or otherwise suitably secured to the inner side of the lock-board 5 near one end thereoi, with its lower end, in the present instance, projecting a short dietance below the` loclboaid An arm 7 is pivoted to the lower extended end ot the plate 6 for vertical rocking movenients at the inner side of the lock-board 5 in parallel relation thereto and has its outer t 'wir limn i of vertical movements l ie window member 4: and on which the lower edge et such member rests. lfhe op` positc end of 'the arm i projects a short distance 'from its pivot and is connected by a spring 9 'to a conver'ent part oi the trame to servo as a means tor counterbalancing the weight of the window member on the arm 7, as well understood in the art.

An operating lever Ois t'ulcrumed to the plate 6 a distance above the arm 7 and has one arm extending from its pivot in the 'general direction of projection et the arm E and connected by a link 11 to said arm, wherebj-,f the arm i" and lever are caused to have rockin movements in unison. The other;A arm o, ne lever projects towards the adjacent side ot' the trame 1 andV has pin and slot .connection 12 witha member 13., which projects rigidly inward from va carrying rod lll toward the pivot ot the lever. rihe rod depends from a slide bl'oclr l5, which is mounted lor vertical sliding movements in a guide 'member 1b mounted in a channel 1i' provided in the adjacent side or upright member oi the trame 1, and at the inner side oi the guide provided in said trame upright tor the window member Ll. The slide block 15 carries a detent 18, which is mounted tor limited reciprocatory inovements therein transversely ot' the guides i6 and is adapted to project into any one ot a set otrnotches 19 provided in the inner wall oitl the guide member 15 and with which the detent may register. A spring 2O normaily holds the detcnt in engagement with a registering notch 19, and a control handle 21 is mounted in accessible position on a disposed in the px .stem oi the detent, which projects through the slide blocl 15, and without the` guide 16 through a longitudinally extending slot 22 therein.

it is evident with this arrangement that any vertical movement of the slide bloclr 15 within the guide 16 imparts a rocking movement to the lever 10 and through the link 11 to the rockerl arm 7 and either effects a raisin@ of the window member 4L or permits lowering ot the same, depending on the direction of movement of the slide block. rlhis forms a very simple and inexpensive window control mechanism of the type in which movement is communicated to the 4on the a" Window member from a reciprocaiory movement o1 a vertically movable control member at the side of they Window.

ln the modified form ot' the invention shown in Q and -t a rack bar and pinion connection bet-Ween the operating rod lliand lever 1G is substituted for the link and pin and slot connection above described. ln this modilied torm ot the invention the lower end of the guide tor the slide block l5 (not shown) which guide is designated 1G is extendeddoivn into the chamber 3 to torni agcide h: f' fveitlcallv reciprocavtory .rack bar 25 attached to the lower end ci the rod l-l, and such yrack bar engages the teeth cia segmental-pinion l0 provided djacent arm oi' the lever l0, the or the rack bar and `pinion through the longitudinal el'ot Qin the e posed side ot the guide.

lt is evident that in either form of the invention, a shitting ci the control handle 2l vertically at a side oi the .Window member communicates a .rocking` movement to the lever l0 and from it to the arm to eliect a raising or lowering ci' the window member.

.l Wish it understood that my invention is yno-t limited to any speciiic construction, ar-

. rangement or form ofthe parts, as it is capable ot numerous modilications and changes Without ldeparting from Vthe spirit of the claims.

kllaving thus described my invention, what il claim as new and desire to secure by Aetters Patent, is,-

l. rlhe combination with a slidable vvindow member, of a frame guiding the movements of the member, an arm pivotally carried by the 4frame for vertical rocking movements and supporting` the Window, counterbalanclng means for the arm, a lever iulcrumed to the trame, means connecting the lever and arm tor imparting rocking movements from one to the other, and manually operable control means guided for vertical reciprocatory movements in a side of the window trame parallel to the movement ofthe Window, and connected to the lever to cause a rocking thereof when lthe control means is moved.

2. The combination with a slidable Window member, of a frame having a chamber receivil said member in its open positionN an arm mounted iior if'eii'tical roclrino ovements Within the chamber and having supporting engagement with the Window member, a counterbalancing means 'for the arm, a lever mounted Within the member t'or vertical rocking` movements and having an arm projecting in the general direction ot projection olf said iirst firm, connection between said lever arm and the Window supporting arm to cause them to have rocking movemen s in unison, a vertical guide in the side trame, a slide bloclr t or vertical reciprocatorv movements in said guide, control means connected to the slide ier operating thel same and operable to releasably secure it in .adjusted position, a rod depending, -from theslide, and connection between the rod and lever Within the chamber i'or imparting a rocking moven'ient to the lever from a vertical reeiprocatory movement of the rod.

3. The combination with a Window Yiframe having a Window opening in its upper portion, a AWindow receiving chambe;q in its lower portion., and a lock-boarc .extending across the upper portion of the chamber at one side thereof, a. Window member slidably mounted in the frame Jfor lowering movemunis in chamber, a plateiixed the i er side ci the lock-board, an arm pivoted to the plate adjacent to the lower edge oi the Iloch-board Jtor vertical rocking` movements and having its outer end projecting below the central portionoi the lower edge voi 'the Window member in supporting engagement therewith, a horizontally disposed ilever pivoted to the plate above said arm for vertical rockingl movements, a linlr connecting` onel arm ol the lever to said ivindovv supporting arm, a vertical guide in the side oi the Window 'frame adjacent to said lever,

and means mounted tor vertical sliding` ANGEL@ ROBERT CLAS.
